LCD

The included LCD has the part number: LH096NT-IF09 made by ShineWorld Innovations.

It is supposed to be compatible to ST7735 LCDs. For which a Micropython library exists.

Camera

Either OV2640 or OV7725.

OV2640 Micropython library for the ESP8266

Supported Features

Features and correct Pin assignments are WIP - I combined them from mcauser and Mythologyli and have adjusted for the obvious changes, I will test the other features as I need them. Buses should work too.

So far these things are verified to work:

• SD Card
• User LED (LED1, Blue, Pin E3)

Build the firmware

Clone the board definitions to your MicroPython ports/stm32/boards folder.

cd micropython/ports/stm32/boards
git clone https://github.com/ikoesters/WEACT_H750VBT6

cd ..
make BOARD=/WEACT_H750VBT6

Flashing via DFU

This board can be flashed using DFU. To put the board in DFU mode, disconnect USB, press and hold the B0 button and reconnect USB then release B0. After installing dfu-util, go the the build folder (ports/stm32/boards/build-WEACT_H750VBT6) and type:

dfu-util -a 0 -D firmware.dfu

Once the upload is complete, disconnect and reconnect USB.
